It takes courage to grow up and become who you really are.

The line frames “growing up” not as simple aging or social conformity, but as the difficult work of self-realization—claiming an authentic identity despite pressures to perform, please, or fit prescribed roles. By calling this process “courage,” the quote suggests that becoming oneself entails risk: disappointing others, losing approval, or stepping into uncertainty. Read in the spirit often associated with Cummings’s celebration of individuality, it elevates personal integrity over external validation and treats maturity as an inward achievement. Its appeal lies in recasting adulthood as a creative, ongoing act of self-definition rather than a fixed status conferred by society.
